Definition
A judicial determination or decision; the act of judging or resolving a matter through judicial authority. The term denotes the formal exercise of judicial power to settle a dispute or pronounce a legal conclusion. It is functionally synonymous with adjudication and judicial determination, though it appears far less frequently in modern legal usage and is treated by most authorities as an archaic or rarified form.
Common Language
Modern common usage (Wiktionary): The act of dijudicating; judgement.
Historical common usage (Webster's 1913): The act of dijudicating; judgment. [R.] — marked rare even in 1913, with the citation to Cockeram indicating its appearance in early modern English word-lists rather than active legal discourse.
The gap between common and legal meaning is negligible here, but the term's extreme rarity in both registers is itself significant. Webster's 1913 flags it as rare, and that rarity extends fully into legal usage. A researcher encountering the term should treat it as a formal synonym for adjudication or determination, not as a term of art carrying distinct legal content.
Common Confusion
Dijudication is most likely to be confused with adjudication, and the confusion is understandable — the two terms describe the same basic act. The distinction, such as it is, is lexical and historical rather than substantive. Adjudication is the established, living term in both common law and civil procedure; dijudication is an archaic variant that surfaces occasionally in older legal dictionaries and period texts. A researcher who encounters dijudication in a historical source should not assume a specialized or different meaning is intended. It is not a term of art in equity, civil law, or any recognized procedural framework that differs from the meaning carried by adjudication or judicial determination.
Why It Matters in Research
The primary research value of this entry is identification and deflation: if you have encountered dijudication in a historical source, you now know what it means and what it does not mean.
The term appears in Black's Law Dictionary and its second edition supplement, which means it will surface in corpus searches of those texts. Its presence there does not indicate it was ever in wide circulation or that it carried specialized meaning in American jurisprudence. It is not a term appearing in reported cases with any regularity, and it carries no doctrinal weight of its own.
Researchers working in early modern English legal texts, colonial-era documents, or heavily Latinate legal writing from the seventeenth and eighteenth centuries are most likely to encounter it. In those contexts it functions as a stylistic variant, not a term marking a distinct legal concept.
One navigational caution: the Rapalje & Lawrence entry in the source material does not appear to contain a substantive definition of dijudication itself — the surrounding entries (DILACION, DILIGENCE) suggest the entry may have been fragmentary or that the term was treated only in passing. Researchers relying on Rapalje & Lawrence for this term should not expect elaboration there.
Historical Dictionary Support
Black's Law Dictionary (both the primary entry and the second edition supplement) defines dijudication as judicial decision or determination. The definitions across these sources are consistent and brief, reflecting the term's status as a simple synonym rather than a developed legal concept. None of the historical dictionaries surveyed attribute distinct procedural requirements, equitable dimensions, or civil law pedigree to the term.
Webster's 1913 marks the term rare as of that date, and the citation to Cockeram — a seventeenth-century English vocabulary list — places the term's active life primarily in early modern usage. The historical dictionaries do not disagree with one another on meaning; they simply have very little to say.
What the historical sources collectively miss is any account of why the term fell out of use. That question is not legally consequential, but researchers working on the history of legal vocabulary may note the contrast between adjudication, which persisted and developed a rich procedural and constitutional literature, and dijudication, which did not.
Jurisdictional Note
No jurisdictional variation is documented or expected. The term does not appear to have been adopted as a term of art in any American state, federal, or civil law jurisdiction. It is effectively jurisdiction-neutral by virtue of its disuse.
